PAPER FEED AND CUTTING MECHANISM.

Application filed May 9,-

The present invention relates to means for manipulating the record paperas it is su plied to and is printed upon by typewrlting machines andautomatic telegraphic machines and the like, when said paper is in theform of a continuous strip stored on rolls, or

in a single, roll.

The important object of the invention is to providea simple andeffective cutting means associated with the platen and platen carriageof the machine and adapted to readily permit the lengths as it isprinted.

Another object is to provide a mechanism of this nature which may bemounted and arranged sothat the cutting means thereof will not interferewith the functioning of the typewriter or the like.

A still further very important object of the invention lies in theprovision of a mechanism of this nature which is thoroughly eflicientand reliable in its operation and which may be manufactured at arelatively low cost.

With the above andnumerous other objects in view as will appear as thedescription proceeds, the invention resides in certain novel features ofconstruction, and in the combination and arrangement of partsas will behereinafter more fully described and claimed. Y

In the drawing Figure 1' is a perspective view of the device embodyingthe features of my invention,

Figure 2 is a fragmentary side elevation thereof, and

Figure 3 is a fragmentary vertical transverse section therethrough.

Referring to the drawingsin detail it-will he seen'that the letter Adenotes a pair of L-shaped members, the longer arms 5 of which normallyextend vertically and the shorter arms 6 of which extend horizontal ly,These L-shaped members A are connected together by rods 7 and 8, theformer being disposed between the arms 5 and the latter between the arms6. These L-shaped members A may be mounted on the carriage of atypewriter or the like in any suitable manner. A stationary cutter bar 9is mounted between the shorter arms 6 intermediate their ends and has acutting edge 10. A rockable member 11 is of oblong construction and atits ends has right angularly disposed flanges 12 which are pivoted as at13 to the ends ofthe shorter arms 6. At

paper to be severed into.

one longitudinal edge this rockable member 11 is formed with a flange 14on which is mounted the movable blade 15 by means of screws 16 or in anyother suitable manner. This movable blade has a finger operatingextension 17 intermediate its ends. Lugs 18 project inwardly from theflanges 12 and springs 19 are disposed between the lugs 18 andstationary cutter member 9 for normallyholding the movable cutter 15spaced therefrom., Platen fingers 20-are pivoted as at 21 on the member11 and have rollers 22 to engage paper passing around the platen. Apaper supply roll is mounted on a roller 25. This roller 25 has a shaft26 one end of which projects through an opening 27 in the upper end ofone arm 5 while the other end seats in a notch 28 at the upper end ofthe other arm 5. Said other arm 5 has its upper end extended outwardlyand laterallv as at 29 so that a rod 30 is projected therethrough andalso through an ear 31 on said other arm 5. The lower end of this rod isformed with an arcuate portion 32 that ensages the adjacent end of theshaft 26 and holds it in the notch 28 through the medium of a spring 33.

From the above detailed description it may be seen that a roll of papermay be mounted on the roller 25 and trained over the platen illustratedat 35 and then up through the space between cutters 9 and 15. After adesired amount of the paper has been printed upon in the usual wellknown manner, the operator may-push down on the finger extension 17 andsever said paper from the remaining portions of the roll.

It is thought that the construction, utility, and advantages of thisinvention will now be quite apparentto those skilled in this art withouta more detailed description thereof. The present embodiment of theinvention has been disclosed in detail merely by way of example since inactual practice it attains the features of advantage enumerate'd asdesirable in the statement of the invention and the above description.It will be apparent that changes in the details of construction, and inthe combination and arrangement of parts may be resorted to withoutdeparting from the spirit or scope v prising a pair of L-sha ed sidemembers each lncludlng a vertlca long arm and a horizontal short arm,a'roller journalled between the upper extremities of the long arms, arockable member mounted between the ends of the short arms, a cuttermounted on the rockable member, a stationary cutter'mounted between theshorts arms, and a spring between the rockable member and the stationarycutter for normally holding the other cutter spaced therefrom, fingersrockably mounted on-the rockable member for f liigaging the platen of atypewriter or the 2'. A device of the class described comprising a pairof L-shaped side me'nibers each including a vertical long arm and ahorizontal short arm, one of the long arms being formed with an apertureand the other with a notch, a. roller having a shaft projecting into theopening and the notch, spring means for holding the shaft in the, notch,a stationary cutter betweenthe short arms, a rockable elongated memberhaving at its ends rightangularly extending flanges pivotally mounted tothe short arms, and a longitudinally extending flange, a movable cutterfixedly attached to the longitudinal and spr1 flange and having anoperating finger, lugs pro ecting inwardly from the end flanges, 'nmeans impinging against the lugs and the fixed cutter for normallyholding the movable-cutter spaced therefrom.

3.'A device of the class described comprising a air of L-shaped sidemembers each inclu ing a vertical long arm and a horizontal short arm,one of the long arms being formed with an aperture and the other with anotch, a roller having a shaft projecting into the opening and thenotch, spring means for holding the shaft in the notch, a stationarycutter between the short arms, a rockable elongated member having at itsends right angularly extending flan es pivotally mouhted to the shortarms, an a longitudinally extending flange, a movable cutter fixedlyattached to the longitudinal flange and having an operating finger, lugsprojecting inwardly from the end flanges, springs impinging against thelugs and the fixed cutter for normally holding the movable cutterspacedtherefrom, and platen fingers pivotally mounted on the rockable member.

In testimony whereof I afiix my signature.
